Title: Improvements in propulsion units for rockets
IPC: F02K9/10
Filed: 1961-11-21
Abstract: 933,847. Propellent charges. R. V. BANCELIN. Nov. 21, 1961 [Nov. 29, 1960], No. 41634/61. Class 9 (1). A propellent charge comprises a casing 1, an axial metal tube 9 lined internally with a refractory material 10 and a charge 11 wholly encased, apart from the combustion surface, in a lining 12. Fig. 2 shows the combustion surface 18 of the charge which forms one side of a longitudinally extending slot 15 and radial channel 17, the other side being formed by a lined metal shield 16 which is an extension of the tube 9. The surface 18 lies substantially in an axial plane of the charge which is so constituted by powders of varying combustion rates that on burning, the surface 18 remains in an axial plane. The charge may have two burning surfaces by forming a further slot and radial channel on the same diameter as that of the channel shown. In this case the second surface is positioned so that burning causes a clockwise rotation of the surface similar to that of the first surface, the centre of gravity of the charge thereby remaining unaltered. Another embodiment involves dividing the charge into sections by metal plates 8<SP>1</SP> (not shown) covered with refractory material and placed perpendicularly to the axis of the charge. Each section has a slot 15 and radial channel 17 angularly displaced with respect to one another about the longitudinal axis, the angle of offset being dependent on the number of sections, e.g. 180 degrees for two and 120 degrees for three sections. In a further embodiment the slot 15 does not extend longitudinally parallel to the axis, but forms a helix whose pitch is preferably equal to the height of the charge. Shields 24, 25 (not shown) also form helices and combustion of the charge is again effected in an axial plane of the charge. The tube 9 may be provided with a slug of powder of cylindrical form having a shaped axial duct.

Title: Improvements relating to nail driving devices
IPC: B25C1/14
Filed: 1963-10-23
Abstract: 1,011,901. Cartridge-operated tools. K. B. E. HANSEN. Oct. 23, 1963 [Oct. 23, 1962; April 29, 1963], No. 41869/63. Heading B4C. A cartridge-operated nail-driving tool comprises a housing 1 having a nozzle 3 at its forward end to receive a nail 5 and a handle 30 at the other end containing a firing mechanism, a striking bolt 10 connected to a piston 11 which is slidable within a bore 2 in the housing, blocking means 37 adapted to render the firing means inoperative until a predetermined force has been applied to the handle, and at least one exhaust port 19 formed in the housing whereby, upon forward movement of the piston beyond the port, air is trapped in the bore and thereby exerts a braking force on the piston. The housing 1 is slidably mounted in a casing 21 which is coupled by means of a bayonettype joint 31, 32 to the handle 30 pivoted at 28 to the casing in order to facilitate loading the tool with a cartridge. The housing is fitted at its inner end with a threaded plug 16 into which the cartridge is inserted, and at its other end with the nozzle 13, the latter being inter. changeable. A breech block 35 is located in the handle and loaded by a spring 44, a firing pin 40 being slidable in the block and loaded by a spring 45; a spring-loaded bolt 37 is adapted to normally block actuation of the firing pin. In operation, after a cartridge has been inserted into the tool, and a rail 5 located in the nozzle, the latter is pressed against the work against the action of a spring 23, thereby causing the inner end of the housing to act against the block 35 and thereby load both springs 44, 45, as shown in Fig. 7. In this position a leaf spring 53 co-operating with a trigger 50 is brought into alignment with the bolt 37 so that, by depressing the trigger, the firing pin is released to fire the cartridge. The loading of the springs, the relative weights of the piston and striking bolt 10 and the braking force on the piston are as chosen in relation to the explosive force that recoil is not transmitted to the operator.

Abstract: 1,131,502. Corrosion resistant coatings. CENTRAL GLASS CO., Ltd. 13 Oct., 1965 [4 Nov., 1964], No. 43421/65. Heading B2K. Iron and steel structures are provided with a corrosion resistant coating by applying a first film of paint to the structure and, while the film is still wet, spreading on the film solid particles of mesh 50 size or smaller size of a granular substance which is inert, and allowing the film to dry at ambient temperature so as to adhere the particles to the film and then applying a second film of paint to the resulting entire surface having said particles adhering thereto and allowing the second film of paint to dry. The process may be repeated by distributing solid particles over the second film of paint before it is dry and applying a third coat of paint over particles in the dry second coat. The paint may contain a synthetic resin and is preferably of a two component type in which a film-forming substance is supported in a carrier and immediately before use a hardening agent added. The granular substance may be silica, sand, metallic oxides, powdered metals. The iron or steel structure may be cleaned by say sand-blasting or by means of a sander, and undercoated once or twice prior to the coating. The paint used may be an asphalt, epoxide resin, polyurethane resin, tar-epoxide and tar-urethane paint. In the example iron and steel structures in an inorganic ammonium fertilizer manufacturing plant having complicated surfaces formed with angle bars, channels, bolts and rivets was treated with sanders, and undercoated with a one component epoxy resin paint. A tar-epoxide paint was then applied and while the paint was still wet silica sand was spread over the surfaces. After the paint had dried a one component epoxy resin enamel paint was applied to completely cover the surface of the grains and to form a smooth film overlying the grains.
